Having fitted a new kitchen mixer tap a couple of days ago, using flexi hose connectors supplied with the tap, I have switched the hot and cold water back on at the valves fitted under the sink. The flow from the cold water is strong, but the hot water is ok but not great. The morning after, the overflow from the large tank in the loft began leaking and when I turned the hot water supply to the kitchen tap off, the leak from the overflow stopped. Since fitting the tap I did notice that there was a sound similar to flowing water coming from the tap. Can anybody suggest what the problem might be here.
The old tap was connected using copper pipes not flexi and the new flexi pipes are a smaller diameter than the old copper pipes, not sure if this is contributing to the problem.
